Answer:
√2
Step-by-step explanation:
3x^2+4x-8+2x^2-4x-2
5X^2-10
5x^2=10
X^2=10/5
X^2=2
X=√2
x^2 - 4/x - 1
it should be the answer. Hope it helped.

Given the following:
Vocalist needed :
First day (a) = 6
For subsequent days : number doubles
Using the relation. :
Sn = a(r^n -1)/(r -1)
Where a = first term = 6
r = common ratio = r3/r2 = r4/r3
Since number doubles after each consecutive day, then ; r = 2, n = 10
Sn = 6(2^10 -1)/(2 -1)
Sn = 6(1024 - 1) / 1
Sn = 6144 - 6
Sn = 6138
